Flaps make sense in a cub to me. Spoilers do not. Reduce power, plane comes down. If you need them to land shorter, you're landing too fast.

[Steve Pierce]

Your too used to flying in the flat lands. Would work great coming in over tall trees.

Flaps make sense in a cub to me. Spoilers do not. Reduce power, plane comes down. If you need them to land shorter, you're landing too fast.

1. Let's say that you are flying over the mountains and you want to land on that strip down in the valley. Deploy the spoilers to loose altitude more quickly. Then retract them when you get in the traffic pattern. Without the spoilers it would take a long time to glide down.

2. Landing in gusty winds, either during or right after touching down deploy the spoilers to help stick the plane to the ground.

3. After touchdown deploying spoilers dumps lift making the brakes more effective.

4. Can be very helpful with Cubs that have long landing gears and spoilers since, with the high angle of attack, they would be more susceptible to wind gust while on the ground.

After you have flown a plane with spoilers, you will find all sorts of things that you can do with them that are not in the book. You will wonder how you got along without them.

Trees grow in flat lands. This is what a slip is for.

1. I still say this is what a slip is for.
2 and 3. A flap retraction will do nearly the same thing if you're landing slow enough.

Any idea on the weight of these? I guess with some of these fat cubs another 10 lbs won't matter.

[Tim]

Chris, I don't think weight is a problem, but from my experience of 2k hours with spoilers your other comments are spot on in my opinion ( for what it's worth )

[Steve Pierce]

They weigh about as much as all the liner tubes in your fuselage Chris. Time, do you figure your spoilers kill a third of the lift of your wing? Wonder if we are comparing apples to apples. mark built them as an experiment, kinda like his ribs and slotted wings. Glad there are folks out their willing to spend the time doing stuff like this.

[Iflylower]

The landings at Valdez are averaging 200 percent of the take-off distances. Spoilers should balance that out.By the way, in nasty winds when you wanna stay stuck to the ground at touch down, spoilers are the stuff! Love em. I would like to try them in a cub

[Tim]

Steve, my stall speed is around 50 mph with the spoilers deployed and 35 or so without ( indicated ).

[Steve Pierce]

When I talked to Mark about his spoilers he said it killed about 1/3 of the lift on the wing. He said it came down quick and could see it being used when coming in short over tall trees. It is more of a toy for him, he said he would not try and get them approved. You gotta know Mark and how he likes to tinker with ideas.

[nesincg]

I don't mean to be saying people shouldn't try out new things. I think this type of mod would be more like a novelty for winning a landing contest, such as nitros and electronic flap dump, then practical. As you know, I'm all for winning a landing contest. I don't think they'd be that helpful in every day use.

I also worry a bit about safety. These are adding complexity to landing which itself can overwhelm some pilots. I say we look into other mods to make our flying safer. Like this:

[Superchub]

Our Local Colorado fish and game has wire cutter kits on the fleet of 185's that they operate. Sharpe cutters on the gear and a cable guide in the center of the windshield to then carry a power line over the top of the vertical stab. I considered welding some cutters on my gear in the build process.

[SJ]

My concern with putting wirecutters on a plane is that it is basically a billboard that says, "Hey, I'm flying low." Sort of like having a gang tattoo on your forehead, you might be the first person they come looking for... but more that I would probably cut myself more times than any wires.

And 35" tires on a supercub with grass stains doesn't?

[SJ]

No, it just says I land on grass, not that I fly so low I might hit power lines while I am landing there.

Back in May one of our local Chumpster guy's was contour flying one of the river valleys and he heard a slight thump and thought maybe he had hit a small bird, he flew around for another half hour and said he was proud of how short he landed, as he was turning around on the grass to taxi to the hangar he noticed something shiny going the other way in the grass on his back taxi. After he got out of the plane he discovered that he was dragging 600' of 1/2" aluminum wire that had got snagged in the gap between the front part of the rudder and the top of the vertical fin.

Thats kinda funny ... and horrible at the same time. I've come very close twice to needing one. You'd think I'd of learned the first time but I love too much flying low. Hazard.

It sure would be an ugly mod.

Is there any possibility he can make them available for experimental Cubs?

[beaver18]

For the wire cutter ,aint pa-18a-150 have them on the landing gear i remember seeing something bolted on the front tube of the landing gears ?

[Steve Pierce]

Yes, he will do that he just doesn't see it being worth going through the certification process. Talked to him a few days ago and he has the video system installed so we can see what the tufts are doing as well as the view out of the windshield.

I have seen them on Pawnee's and a Citabria.

[MainlandCub]

You are right. A half round piece of tube with a blade on the front. Attached at the top underneath the front undercarriage mount bolt. In New Zealand we attached mudguards to them. I have a set of these stashed away.

Just wondering, wouldn't they work better inboard of the ailerons so that they were still working, or is the gas tank in the way.

Be sure to keep us posted Steve.

Thanks,
Andrew.

[Steve Pierce]

I thought they were between the ailerons and the tank.

[Steve Pierce]

They go from just outboard of the tank to the "N" strut in the wing. On a DC extended wing it blanks out a 14 of the flap (they are extended) and 1/3 of the aileron.

[Amy]

You talking about these

Attachment 8051

Mark told me only two words could accurately describe them: 'Holy ****!'

He wasn't kidding.

[12 Geezer]

Dynon introduced a portable attitude indicator. Since it is "portable it can be used in a certified aircraft. This would be a really neat tool to have in your panel just in case you get caught in the Wx unexpectedly.

here is a link to more info.

Now that this unit has been out and in use for a while, what user experiences can be reported? Sure looks like an outstanding unit, that could replace the old venturi / turn & bank system. Reports?

[12 Geezer]

Bump. I'm really curious about any experiences - -
Thanks!

Gordon,
Thats a lot of money for just a gyro. If u have a pc display already u can add a e-gyro for much less. I have a e-gyro-usb which can plug into just about anything, its $595 from www.pcflightsystems.com . I use it on a Helm X650. It's nice to have the AH intigrated into the synthetic vision/gps/weather all on one touch screen. I've left it on while spraying just to see if it can keep up. It does better than I would have thought it would, but I can still tumble it. Nice to know I can still out fly a computer, in normal flight it does fine. It's still jittery, but would keep the dirty side down in a pinch. I wouldn't drop $1500 on something that can't be upgraded. As fast as this technology is evolving it will probably be obsolete faster than u can get it out of the box.

[Barry.LeBlanc]

Why Mode C
For aircraft flying blow 18,000 feet Mode C will continue to be used indefinitely. There is no requirement for aircraft flying at those altitudes to equip with more costly Mode S. It is true that Mode S will provide traffic and meet the 2020 ADS-B mandate, if the aircraft is equipped with an approved ADS-B GPS. However, we believe that a better solution for meeting the ADS-B mandate is UAT (Universal Access Transceiver). UAT has a much broader bandwidth than Mode S which allows it to transmit and receive more information. There are already many UAT receivers on the market that will receive both TRAFFIC and WEATHER, and there is no subscription fee for the weather. In contrast Mode S, because of its narrow bandwidth, will only provide traffic information. The UAT solution to ADS-B still requires the use of a transponder, either Mode S or Mode C. If the aircraft is equipped with UAT, the Mode S serves no purpose.

Why the STX 165
The STX 165 is a small, light weight Mode C transponder designed to fit a ½ 3ATI instrument hole, leaving more center stack space for today’s growing avionics packages such as the Garmin GTN 750. The STS 165 features a built-in 35K foot encoder simplifying installation, three timer functions, a pressure altitude readout and with the optional Sandia OAT probe, OAT display, Density Altitude display and an Icing Alert.

Is this the same Boz we know with the stripped out Super Cub with a huge ax in the back.

[SuperCub MD]

Don't worry Steve, I haven't completely gone to the dark side, that fancy stuff is for the other planes. The axe is still the most intricate piece of optional equipement in the Cub.

[Steve Pierce]

LOL, That is good to hear Mark.

HA! We miss seeing you at New Holstein. You need to get that corn on a different schedule.
